The Republicans know full well what a destructive force he is, and they know to one extent or another he's going to do them damage. But the core desire of the Libertarian wing of the party is the decimation of the Federal Government, so they'll accept a few body blows in service of the cause.

The least-harm principle. There's essentially universal agreement that low (dietary-range) levels of lithium are not harmful, while the research as a whole is strongly suggestive of a benefit (but has not yet met the standards of, for example. an EPA regulatory standard for lithium in drinking water). Lithium, at the doses necessary, costs basically nothing, takes seconds to take, and is orders of magnitude away from the levels where potential toxicity symptoms can arise. To me, that's an easy call. Also, Alzheimer's runs in my family, so there's an extra factor weighing on the scale.

Nothing weird about sodium fluoride, fluorosilicic acid, or sodium fluorosilicate. Sodium fluoride is a simple salt, dissociates immediately upon dissolution to Na+ and F-. Fluorosilicic acid and sodium fluorisilicate result in a fluorosilicate ion (SiF-2) which rapidly hydrolyzes to Si(OH)4 + 6F- + 4H+. Si(OH)4 (orthosilicic acid) is the form of soluble silicon which plants and diatoms consume and is perfectly normal in water in the tiny amounts from fluoridation (like 6 micromolar concentration). Ocean surface water near Antarctica for example is up to ~80 micromolar concentration. And it goes without saying that minuscule amounts of sodium in water are also perfectly normal. The addition of the fluoride ion is the only actually meaningful impact.
